Abstract (en)
In a power supply system, an inductance L is connected between a rail at a voltage V, and a rail at earth through a switch S. When the switch is opened, a current i<sub>1</sub> flowing from the inductance L is directed to a third rail through a diode D, voltage on the third rail rising to V<sub>1</sub>. The system may function as a dc to dc converter with an output voltage between the V<sub>1</sub> rail and the V<sub>2</sub> rail equal to V<sub>2</sub>-V<sub>1</sub>. The system may alternatively be used in, for example, a reluctance motor drive, in which case a further inductance with associated switch and diode is included in the circuit in inverse configuration to prevent excessive voltage rise on the third rail.
